How to Change the Coolant in a 2017 Honda CRF150F: Step-by-Step Guide

Shop parts for a 2017 Honda CRF150F Dirt Bike.

Routine coolant changes are essential for your 2017 Honda CRF150F to maintain optimal engine performance – protecting your bike from overheating, corrosion, and premature engine wear. The CRF150F features a simple air-cooled, four-stroke engine, making the process straightforward even for new do-it-yourselfers.

What Makes the 2017 CRF150F Unique?

The CRF150F uses an air-cooled SOHC four-stroke engine, meaning it does not have a liquid cooling system or radiator like the CRF150R.
Instead, it relies on airflow and oil to keep engine temperatures in check. This design reduces maintenance complexity and eliminates the need for typical liquid coolant changes accustomed to many modern dirt bikes. The only cooling system fluid in need of regular attention is the engine oil.

If You Have a CRF150R, Not an F Model

The CRF150R is equipped with a radiator and requires periodic coolant flushes and refills. Be sure to reference your exact model before following any traditional coolant change guides, as the steps differ entirely between the R and F models.

Maintaining Engine Cooling on the CRF150F

  • Keep engine fins free of mud & debris. The air-cooled system depends on exposed fins to dissipate heat – always keep them clean.
  • Use high-quality, correct-grade oil for your climate to help control internal engine temperatures.
  • Check your oil regularly and change it as recommended in your owner's manual.

Common Pitfalls

  • Confusing the CRF150F with the CRF150R. These are completely different engines – the F is air-cooled (no coolant), the R is liquid-cooled (requires coolant changes).
  • Ignoring engine cleanliness. Caked-on mud or dirt can lead to dangerous overheating in air-cooled bikes.

Summary: There Is No Traditional Coolant Change on the CRF150F

Your 2017 Honda CRF150F does not require a coolant change like liquid-cooled dirt bikes. Focus instead on oil and air filter maintenance, regular cleaning, and periodic valve checks for the best performance. If your CRF150F ever runs unusually hot, check oil level, fin cleanliness, and airflow around the engine.
